Assuming you mean the exhaust and/or intake valves.
# Remove the heads # Borrow, rent or buy a valve spring compressor # Use the spring compressor to compress the springs (one at a time of course) # Remove the valve stem "keepers" # Push the valve out through the head.
When the center exhaust valves are side by side (siamese), it's a small block (EIIEEIIE). Big blocks are symmetrical (EIEIEIEI).
Chilton, Motors, or Haynes manual should give a detailed description.
take off the valve covers, and the rocker arms will have adjusting nuts on them, tighten them to zero lash and the back off 1/4 turn.
The valves won't be able to fully close at higher rpm.
If you have the heads off then the small valve will be the exhaust. Now if the heads are still on the block then remove the valve cover and look at the valve springs. Starting at the front of the head and moving towards the rear the valves will be in this order. E I I E E I I E The E stands for exhaust and the I stands for intake.
Small block
It is a small block
"The v8 350 is a small block Chevrolet motor.....................it became a big block at 396cubic inches......so anything smaller is a "small" block" this is a little misleading. a 350 is indeed a small block. a 396 is indeed a big block. but you can have a small block that is (internally..cubic inch wise) actually larger than a big block. for example GM made a 400 cubic inch small block. internally it is a larger engine than a 396, but the outer dimensions of the 396 are larger than the 400 small block. and the external dimensions and cylinder head design are what make a small block a small block, and a big block a big block. a small block engine simply has a physically smaller block...a big block is called a big block because it's block is bigger than that of a small block.
Big, and small block take different pumps, yes.
That would be a small block.

The tricuspid and bicuspid valves block blood from coming back into the atria.
